Specification of Letters Patent.

Application filed a ry 11,1906. Serial No. 295.664-

To all whom it may concern:

Be it known that I, J S ROGERS, a citizen of the United States, residingat Bronx borough, in the county and State of New York, have invented newand useful Improvements in Antifriction Devices, of which the followingis a specification.

By means of this invention the pressure or friction of a vehicle on theaxle or bearing is counteracted or reduced, as set forth in thefollowing specification and claims, and illustrated in the annexeddrawings, in which Figure 1 is a sectional side elevation of arunning-gear or a truck embodying this invention. Fig. 2 is an end view,partly in section. Fig. 3 is aperspective view of a magnet. Fig. 4 is asectional side elevation of a modification.

In the drawings the letter a designates the wheels, and b is an axle.The wheels of a railroadcar can be taken as an example, but nolimitation of this invention is thereby in tended. The frame c.is hungfrom or has its bearings on the axle, and this frame is made to carrythe vehicle or support the weight of the car or vehicle body.

A magnet is shown at d, and the attraction between the magnet and theaxle will tend to lift or counteract the pressure of the frame orvehicle on the axle. The friction of the frame on its bearings or thepressure of its contact on the axle is thus reduced or counteracted. Theaxle thus serves as an armature with relation to the magnet. An armatureportion or suitable enlargement on the axle can be provided, as seen at0.. The magnet can be an electromagnet of suitable construction, andvwhen suitably vitalized such magnet will cause counteraction orreduction of friction, as stated. The supporting-frame 0 can be of anysuitable construction, and the magnet being secured to this frame andthe latter being on the axle a suitable lifting action by the magnetwill be obtained, as required. By means of an armature, as seen at e,the attraction can be increased. The axle can have an enlargementforming an armature, as shown in Fig. 2, or, as shown in Fig. 4, theaxle may carry the magnet, and the armature of curved or suitable formcan be secured in proximity to the magnet. A reversal of parts, such asapplying the magnet to the axle and the armature to the frame or to thevehicle to accomplish the desired result is, of course, included in theinvention. Such and similar modifications are to be considered asclaimed herein.

The armature and magnet can be the laminated structure usual in magneticconstructions.

This invention can be suitably applied. For example, on electric motorsorvehicles when the electric fluid is turned on it can at the same timebe made to vitalize the anti friction magnet, or the device could bearranged in any other desired suitable wayas, for example, by having adynamo or electric generator on the vehicle; or other suitable operatingmeans can be employed to gen.- erate and control the electric current.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A vehicle having the body and axle respectively provided with magnetand armature portions for counteracting the pressure of the body on theaxle.

2. A vehicle-axle combined with a frame having bearings on the axle, anda magnet connected to the frame for exerting attraction on the axle.

3. A vehicle-axle provided with an armature portion, a supporting-framehung on the axle, and a magnet for exerting attraction on the armatureportion to counteract the pressure or weight of the frame.

4. A vehicle-axle combined with a frame hung on and having a magnetbelow the axle for counteracting the weight or pressure of the frame.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
